VirtualBox

• Increase Virtual Disk space
  • VBoxManage modifyhd <absolute path to file> --resize <size in MB>

VBoxManage modifyhd wim.vdi --resize 20000

Container Docker

• Web site Docker

Install Docker

• Install

 apt-get install docker.io

Network Configuration

• Configuration to share the same network
• Edit /etc/network/interfaces to add a "bridge" you may have to reconfigure your firewall
• Add br0 to auto
• Remove ip assignement or dhcp of eth0
• Add br0 bridged to eth0

Ip Address assigned by dhcp

# Interfaces(5) file used by ifup(8) and ifdown(8)
auto lo br0 eth0
iface lo inet loopback

iface eth0 inet manual

iface br0 inet dhcp
        bridge_ports eth0

Ip Address Fix

1. Interfaces(5) file used by ifup(8) and ifdown(8)

auto lo br0 eth0 iface lo inet loopback

iface br0 inet static

       address 10.1.1.1
       netmask 255.255.255.0
       broadcast 10.1.1.255
       network 10.1.1.0
       bridge_ports eth0

Update Docker Configuration to use the bridge

• Edit /etc/default/docker.io
• Add private dns (--dns 192.168.1.1) and bridge (-b br0) to Docker Option line

 DOCKER_OPTS="--dns 8.8.8.8 --dns 10.10.1.1 -b br0"

Owncloud

• Add the repository

sudo sh -c "echo 'deb http://download.opensuse.org/repositories/isv:/ownCloud:/community/xUbuntu_14.04/ /' >> /etc/apt/sources.list.d/owncloud.list"

• Add Key

wget http://download.opensuse.org/repositories/isv:ownCloud:community/xUbuntu_14.04/Release.key
sudo apt-key add - < Release.key

• Install

sudo apt-get update
sudo apt-get install owncloud

Apache Svn Server

1: Install Apache HTTP server and required modules:

sudo apt-get install libapache2-svn apache2

2: Enable SSL

sudo a2enmod ssl
sudo vi /etc/apache2/ports.conf

Add or check that the following is in the file:

<IfModule mod_ssl.c>
    Listen 443
</IfModule>

3: Generate an SSL certificate:

sudo apt-get install ssl-cert
sudo mkdir /etc/apache2/ssl
sudo /usr/sbin/make-ssl-cert /usr/share/ssl-cert/ssleay.cnf /etc/apache2/ssl/apache.pem

4: Create virtual host

sudo cp /etc/apache2/sites-available/default /etc/apache2/sites-available/svnserver
sudo kate /etc/apache2/sites-available/svnserver

Change (in ports.conf):

"NameVirtualHost *" to "NameVirtualHost *:443"

and (in svnserver)

<VirtualHost *> to <VirtualHost *:443>

Add, under ServerAdmin (also in file svnserver):

SSLEngine on
SSLCertificateFile /etc/apache2/ssl/apache.pem
SSLProtocol all
SSLCipherSuite HIGH:MEDIUM

5: Enable the site:

sudo a2ensite svnserver
sudo /etc/init.d/apache2 restart

To overcome warnings:

sudo vi /etc/apache2/apache2.conf

Add: "ServerName $your_server_name"

Add, under ServerAdmin (also in file svnserver):

SSLEngine on
SSLCertificateFile /etc/apache2/ssl/apache.pem
SSLProtocol all
SSLCipherSuite HIGH:MEDIUM

6: Adding repository(ies): The following setup assumes we want to host multiple repositories. Run this for creating the first repository:

sudo mkdir /var/svn
sudo svnadmin create /var/svn/mysvnrepository
sudo chown -R www-data:www-data /var/svn/mysvnrepository
sudo chmod -R g+ws /var/svn/mysvnrepository<

6.a. For more repositories: do step 6 again (changing mysvnrepository Name)

7: Add an authenticated user

sudo htpasswd -c -m /etc/apache2/dav_svn.passwd $user_name

8: Enable and configure WebDAV and SVN:

sudo vi /etc/apache2/mods-available/dav_svn.conf

Add or uncomment:

<Location /svn>
DAV svn

# for multiple repositories - see comments in file
SVNParentPath /var/svn

AuthType Basic
AuthName "Subversion Repository"
AuthUserFile /etc/apache2/dav_svn.passwd
Require valid-user
SSLRequireSSL
</Location>

9: Restart apache server:

sudo /etc/init.d/apache2 restart

10: Validation:

Fired up a browser:

http://localhost/svn/$REPOS https://localhost/svn/$REPOS

Commit something:

svn import --username $user_name anyfile.txt https://localhost/svn/$REPOS/anyfile.txt -m “Testing”

Accept the certificate and enter password. Check out what you've just committed:

svn co --username $user_name https://localhost/svn/$REPOS

Server Setup

Open DKIM

Web site [1] For each domain:

• Create folder

  mkdir /etc/opendkim/keys/domain_name 

• Update configuration file /etc/opendkim/KeyTable
• Generate Key

  opendkim-genkey -s mail -d domain_name

• Change Owner

  chown opendkim: /etc/opendkim/KeyTable/domaine_name/mail.private

• Copy the key (mail.txt) into the dns record.
